1 Product Description
1.1 General Description
The S661 rate counter fits a 1/8 DIN standard cutout and is perfect for tight spaces,
extending only 3.24” (82mm) behind the panel. The unit is UL listed. The unit is for in-
door use at altitudes up to 2000m, temperatures between 0° and 40°C and installation
category III, pollution degree 2.
The counter is powered from 120 or 240 VAC. The nonvolatile EEPROM retains all
programming and count information when power is removed or interrupted.
Display scaling, preset values and all menu functions are easily programmed from the
front panel, following easy-to-use word prompts. Front panel reset disable and pass-
word lockout protection features guard against unauthorized or accidental changes.
The counter accepts count rates up to 30 kHz and pulses from different types of sen-
sors, including Quadrature, CMOS or TTL circuits and PNP or NPN devices.
The optional, field-replaceable single/dual relay module enhances the counter from a
passive display device to an integral control element for your application. The counter
has latching, boundary or timed (0.01 to 599.99 seconds) output modes.
An optional 12 VDC (100mA) excitation output module can provide power for external
sensors.

2 Hardware Setup
2.1 PanelInstallation
The S661 1/8 DIN counter requires a standard 1/8 DIN panel cutout of 1.77” (45mm)
high by 3.62” (92mm) wide. To install the counter into a panel cutout, remove the clips
from the side of the counter. Slide the counter through your panel cutout, then slide
the mounting clips back on. Press evenly to ensure a proper fit.

1. Remove module from case by inserting a screwdriver into tab slot opening at top of input
module. Apply pressure to release module from case. Repeat procedure for tab located on
underside of module and then slide module away from the case.
2. Refer to appropriate sections to congure switches or jumpers for proper operation.
Table 1 can be used to identify modules and their associated detail paragraph.
3. Install module by carefully aligning module edges with slots in case and pressing forward
until tabs (on top and bottom) engage.

2.3 120/240 VAC Power Module
Never connect AC mains (hot or neutral) to the Reset or Common terminals!
2.4 Standard Input Module
NOTE: A fusible link is not provided on this module.
A ½ Amp Time Delay fuse, Bussman MDL ½, or similar is required.
Remove power before wiring option modules.
The AC power module allows the S661 to be
operated from standard 50/60 Hz line power.
The power module will be congured as 120
VAC or 240 VAC per markings on the back
panel. Ensure the input rating of the supply
matches your line voltage. The power supply
module has provisions for a hard-wire Alarm
Reset. This control can be a switch, relay
contact or solid state device. Actuation is
immediate upon an active Low for at least
2.5ms to this terminal. The reset circuit is
independent of the power circuit.

Figure 7. Standard Input Module Default Settings
DIP switch SW1, figure 7, is used to set up the counter to conform to the electrical
characteristics of the sensor or signal being detected. Switch positions 1-3 config-
ure channel B, while switches 4-6 configure channel A. These switches select bias
(threshold voltages), low pass filter (enable/disable) and sensor type (Sink or Source).
Refer to the documentation that accompanied the sensor for related information. The
sensor can most likely be matched to one of the typical switch settings shown in figure
8 and figure 8a.
Note: The input boards are designed so that selecting sourcing or sinking is
based on the type of sensor that is being used. If a PNP (sinking) sensor is be-
ing used, set the input board for sinking also (switched 3 and 6 = OFF).
If channel B is not used, default settings for switch positions 1 through 3 should be se-
lected. Default settings are provided in Table 2.
The input module also provides for a user input signal. On the S661, this input per-
forms a Display Hold. While active, the rate value shown on the display is “frozen.”
Internal measurements and output controls continue to operate.

The S661 can accept inputs from many different sensors. The A and B channels may
be configured independently as shown in Table 2. Figures 8 and 8a have examples of
some typical sensors and the wiring connections that would be used.

2.5 Quadrature Input Module
The Quadrature / Universal Input Module has two operational modes: Quadrature
mode and Standard mode. Quadrature mode is selected by positioning JP1 and JP2
on pins 1 and 2. Standard mode is selected by placing JP1 and JP2 on pins 2 and 3
(see Figure 10 for details). The Quadrature mode supports a wide range of encoders
including the Simpson SE series.
While in Standard mode, this module works similarly to the Standard Input module,
with the added capability to selectively invert A, B, and User input signals. The Input
module also provides for a User input signal. On the S661 this input serves as a Dis-
play Hold. While active, the rate value shown on the display is “frozen.” Internal mea-
surements and output controls continue to operate.
NOTE: If B channel is not going to be used, use the default switch settings for
SW1 positions 1 through 3. Default settings are provided in Table 3.

In both modes, the state of the User input signal can be selected as active high or ac-
tive low. DIP switch SW1 configures the counter to match the specifications of the ac-
companyingsensor. When shipped from the factory, the counter is set for X1 quadra-
ture, as shown in Figure 10and Table 3:

2.6Excitation Module
Figure 11. Wiring Encoder w/ Excitation Supply
12 VDCExcitation Module
The Excitation Module can supply 12 VDCat up to 100 mA for external sensors or en-
coders. This excitation is isolated from the counter internal logic supply. When using
sensors or encoders that do not have a signal return or imply a signal return that is in
common with the supply voltage, a common attachment that ties the excitation supply
to the logic input common may be required. Examples of this appear in figures 8, 8a,
11 and 12.
